To [2 7] ll'imm/ it may (307L067'IL:

Be it known that we, JOHN C. SUMMERS and T'IOMER E. YODER, citizens of the United States, residing at Mounthope, in the county of Holmes and State of Ohio, have invented certain new and useful Improvements in Windmills; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the figures of reference marked thereon, in which Figure 1 is a perspective view of windwheels, showing the same properly mounted and connected together with the different parts pertaining to the governing of the wheel. Fig. 2 is an edge view of the windwheels proper, showing the shaft-supporting head in section and illustrating the hand regulating devices. Fig. 3 is an enlarged view of the regulating blade mechanism, showing a transverse section of the regulating-arm and illustrating the parts properly connected to the fixed hollow shaft. Fig. 4 is a detached view of the regulating-blade and the manner of connecting the same to its arm. Fig. 5 is a view showing the vaneregula-ting gear and shaft.

The present invention has relation to windmills and to that part of a windmill designed to regulate the speed and it consists in the novel construct-ion hereinafter described, and particularly pointed out in the claims.

Similar numerals of reference indicate correspondingp arts in all the figures of the drawmgs.

In the accompanying drawings, .1 represents the post or support, which is securely connected in any convenient and well-known manner to the top of the frame 2. The post 1 is formed hollow and is so formed for the purpose of receiving the vertical shaft 3, to the top or upper end of which vertical shaft is attached the gear-wheel 4, which gearwheel meshes with the gear-wheels 5, which gear-wheels are fixed to and rotate with the wind-wheels 6, which wind-wheels may be of the form shown in the drawings or they may be differently formed without departing from the nature of our invention. Owing to the fact that the wind-wheels within themselves form no particular part of the present invention except for the pur )ose of preventing the wind from striking the blades of the wheels when the wheels are edge to the wind, said wheels are provided wlth the bands 7,

which bands act as wind-brakes to the blades of the wheels.

To the post or support 1 is attached or formed integral therewith the head 8, which head is for the purpose of forming a support to the various parts of the windmill proper and to which head is securely fixed the hollow bar or shaft 9, which hollow shaft is extended in one direction to considerable length and is so extended for the purpose hereinafter described. ithin the hollow shaft is located the shaft 10, to the outer for ward end of which is securely attached the arm 11, and to which arm is connected the yoke 12, and to said yoke is attached the link 13, said link being pivotally attached to the regulating-blade arm 14, which regulatingblade arm is pivotally attached to the bars 15, which bars are joined together at their top or upper ends, and to the top or upper joined ends of the bars is attached the shaft 16 by means of the nuts 17 or their equivalents. Upon the shaft 16 is located the bearing-nut 18, and the top or upper end of the shaft is provided with the bearinghead 19, which bearing nut and head are located in the bearing-sockets 20 and 21,which bearing-sockets are formed in the head-connecting thimble 22.

To the thimble 2 2 is attached the connecting-head 23, which connecting-head is securely fixed to the shaft or rod 9 by means of suitable set-screws 2st or their equivalents. To the bottom or lower portion of the thimble 22 is connected the cap 25 and to which cap is connected the housing 26. The housing 26 is preferably cylindrical in cross-section and is for the purpose of inclosing the bars 15 and the lower portion of the shaft 16 and is also for the purpose hereinafter described. For the purpose of preventing any accumulation from the freezing of water the housing 26 is closed at its top or upper end by the cap 25 and open at its bottom or lower end. The housing 26 is provided with the curved slots 27, which curved slots are located diametrically opposite each other and through which slots the blade-arm 14 is extended, as illustrated in Fig. 1.

To the inner or wheel end of the blade-arm 14 is attached the head 28, which head is provided with a series of apertures 29, which apertures are for the purpose of changing the angularity of the blade-holding stem 30, to which blade-holding stem is attached the regulating-blade 31. The shaft 10, to which the arm 11 is attached, is extended through with reference to the bracket 40, to which the hollow shaft 9 and continued beyond the rear wheel 7, and to the rear end of said shaft is attached the toothed segment 32, which toothed segment meshes with the toothed segment 33, which segment is securely at tached to the vane-shaft 34, to which shaft is securely attached the vane-holding rods 35 and 36, which rods support and hold the vane 37. that its normal position will be that illustrated in Fig. 1, and when in the position illustrated in Fig. 1 the vane 37 will be parallel with the current of wind, or substantially so, and the wheels practically at right angles to the current of wind and to the vane; but when the velocity of the wind is excessive it will have a tendency to elevate the regulating-blade 31, thereby turning the blade-arm 14 upon its pivotal oint, which in turn depresses the rear en of said arm and rocks the shaft 10 through the intermediate connections between said shaft and the arm 14, which rocking movement rotates the toothed segments 32 and imparts rotary movement to the toothed segment 33 and rocks the vane-shaft 34, thereby throwing the vane into wind and the wheels out of wind, thereby re ulating the speed of the wheels. It will of course be understood that the regulating-blade 31 will act as a governor to hold the wheels at the proper angle with reference to the wind-current. It will be understood that when the vane 37 is brought into wind the different parts of the windmill carried by the support 1 will be rotated around a vertical center or axis, and when so rotated the housing 26, together with the different parts carried thereby, will have a planetary movement around or partially around the vertical axis of the windmill-head of the windmill proper. F or the purpose of allowing the regulating-blade 31 to remain parallel with the current of wind, or substantially so, the curved slots 27 are provided, which curved slots allow the arm 14 to partially revolve in a horizontal plane during the time it is rocked in a vertical plane by the current of wind. It will be understood that the regulating-blade 31 will fall automatically when not acted upon by an excessive current of wind or when the velocity of the wind is normal or below, and for the purpose of allowing the arm 14 to move in a horizontal plane the bars to which the arm is pivoted are suspended by the shaft 16, andfor the purpose of reducing the friction of said shaft the ball-bearings 38 are provided.

In use it is frequently desirable to set the wheels 7 out of wind independent of the regulating-blade 31, and in order .to accomplish this we provide mechanism by which the vane 37 can be brought at an angle to the current of air, which mechanism consists in an upright support 39, held in fixed position The regulating-blade 31 is weighted, so

upright support is pivotally attached the rock-bar 41, to one end of which rock-bar are connected the rods 42, which rods extend downward and are connected to the sliding head 43, which sliding head is swiveled to the head 44, which heads 43 and 44 are adapted to move vertically upon the support 1. To the head 44 is attached the pull-rod 45, which pull-rod extends downward a sufficient distance to be easily reached by a person standing upon the ground or platform. To the opposite end of the rock-bar 41 is attached the rod 46, the bottom or lower end of which is attached to the arm 47, so that when the pull-rod 45 is drawn downward it will elevate the rod 46, and by means of the toothed segments the vane 37 will be brought at an angle tov the current of air, and thereby turn the wheels 7 out of wind and out of action by bringing the wheels into position so as to bring their axes at right angles to the current of air.

It will be understood that the wheels 6 are to be provided with the hubs 48, which hubs are mounted upon the hollow shaft 9 and held in proper position by means of the head 8 and the collars 49.

It will be understood that the blades of the Wind-wheels should be set at opposite angles, so that the wheels will rotate in opposite directions, thereby causing the wheels 5 to rotate in opposite directions and transmit their power to the gear-wheel 4 and the powershaft 3.

Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. In awindmill, the combination of a horizontal hollow shaft having mounted thereon wind-wheels, said wheels provided with blades located at opposite angles, gear-wheels rota-- table in opposite directions with the opposite rotations of the wind-wheels, a power-shaft provided with a gear-wheel meshing with the oppositely-rotating gear-wheels upon the hollow shaft, a shaft located in the hollow shaft and provided with an arm, a regulating-blade arm pivotally attached to vertical rotatable bars suspended by a rotatable shaft, and the shaft located within the hollow shaft upon which the wind-wheels are mounted, a regulating-blade secured to the pivoted arm, a vane, and means for operating the vane by the movement of the regulating-blade, substantially as and for the purpose specified.
